The present invention provides a medical device comprising: a main body; and two or more fixed casters and at least one floating caster, which are connected to a bottom portion of said main body and support said main body, wherein said floating caster is capable of floating in the vertical direction relative to said main body.

A mobile X-ray imaging apparatus has an angle sensor and a movement calculation circuit that controls the driving of drive wheels based on the turning angle of auxiliary wheels relative to a straight moving direction of the base unit when a fine movement switch instructs movement of the base unit in the fine movement mode. The turning angle of auxiliary wheels is detected by a turning angle sensor and the rotation of the pair of drive wheels is controlled by the movement calculation circuit as the auxiliary wheels turns to the straight moving direction.

A security bin for use in separating and X-ray scanning personal belongings as part of a security screening process, wherein the bin comprises cantilevered handles comprising at least one bin identification number that is detectable by X-ray. The handles extend outwardly from a perimeter side or edge of the bin, wherein the perimeter defines an opening of the bin. The security bin further comprises an identification number that is optically detectable and corresponds to the identification number that is detectable by X-ray.

Apparatuses and methods for mounting an object to a pallet jack are disclosed. One apparatus includes a base, a hook, and a clamping element. The base is sized to be positioned on a head of the pallet jack. The hook is sized to engage an underside of the pallet jack. The hook is movably coupled to a front of the base such that a distance between the base and the hook is adjustable. The clamping element is coupled to a rear of the base. At least a portion of the clamping element is positioned to extend underneath the head of the pallet jack when the base is positioned on the head of the pallet jack.

A device for lifting and transporting sheet material includes a base portion; wheels on which the base portion is supported; a mast that extends upwardly from the base portion; a boom that extends from a first end outwardly from the mast to a second end; a supporting head that is configured to support sheet material; and a pivot coupling at the second end of the boom. The pivot coupling is arranged to couple the supporting head to the boom, and enable the supporting head to be rotated about a pivot axis between a first position in which sheet material supported by the supporting head is in a generally transverse orientation relative to the boom, and a second position in which the angle between sheet material supported by the supporting head and the boom is reduced.

A mobile transporter is provided. The transporter includes a lower frame structure, an upper frame structure, a plurality of posts coupled to the lower frame structure and the upper frame structure, a roller assembly provided on the lower frame structure, a panel that extends from and retracts into the transporter, and a wheel that supports the panel, when the panel is extended from the transporter between a second partially open state and a fully open state.

A wheelchair or wagon made of light material that is resistant to corrosion from the salty atmosphere that may be found in beaches and that can be folded to fit in the back of conventional cars, minivans or SUVs without the need for disassembly. In one form, the wheelchair can be used to push a person that is seated upright on sandy terrain, with the use of inflatable balloon tires and a footrest to protect the feet. In another form the frame may be made longer and shorter for a person to be seated in a prone position with their legs stretched out and the wagon pulled with the use of a foldable handle at the front.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.

A concrete/cement resurfacing machine integrates a dust collection subsystem and an overlay mixing/distribution subsystem, enabling a single operator to steer the machine to a desired floor location and deposit mixed, cementitious overlay material. The combination of dust collection and overlay mixing saves considerable time and achieves improved results, eliminating the need for separate vacuum machines while reducing the risk that dust will be released as bags of dry ingredients are added to the mixing tank. A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.
